+summary: "34-key Ferris Sweep keymap on Hands Down Vibranium with an alpha thumb. Magic keys finish whole words from context (b+magic → because); adaptive keys rewrite same-finger bigrams into rolls (n+r → ng, l+r → ll). Low finger travel, in-roll bias, arrows reachable from the home row. No home-row mods — timing-robust, no tap-vs-hold misfires."
